Hello,

(a+b) (a-b) = a² - b²

or  a² - b² = (a+b) (a-b)

Step-by-step explanation:

3 ( (x+4)² - 9 ) = 3 ( (x+4)² - 3² ) = 3 (x+4+3) (x+4-3) = 3 (x+7) (x+1)

- (x+9)² + 1 = - ( (x+9)² - 1²) = - (x+9+1) (x+9-1) = - (x+10) (x+8)

Find 1/9 of 3/4 of 24
fomenos
First, find 3/4 of 24. 24/4=6, 6x3= 18. Now, find 1/9 of 18. 18 divided by the denominator, 9, is 2. Since the numerator is one, our answer remains as 2. So yeah, the answer is 2.

Answer:

0

Step-by-step explanation:

1) Multiply the first equation by -3:  -6x - 3y = 12

2) Substitute 2x + 12 for -3y in the above equation, obtaining:

-6x + 2x + 12 = 12

Then -4x = 0, and x = 0.  Letting x = 0 in the first equation, we get:

0 + y = -4, so y = -4.

The x-value at the intersection of the lines is zero (0).

That intersection is at (0, -4).
